First half losses = 84/2 * 3/7 = 18

Second half losses 84/2 * 5/14 = 15 add them together.......

I'll latex it to make it a bit easier

EP's answer was great though :)

$\frac{3xy}{x}-47$

This is the same as crossing out the x's.

$3y-47$

I think EP also had a typo or something.. the question was 3xy, not 34xy

Squares between 100 200 inclusive 100 121 144 169 196

101 197 add them together ! *** edited ***

Let's start by listing out the perfect squares that are between 100 and 200.

11^2=121

12^2=144

13^2=169

14^2=196

Now, let's see if the numbers that are 1 or 2 more than these squares are prime.

121+1=122 NOT PRIME

121+2=123 NOT PRIME

144+1=145 NOT PRIME

144+2=146 NOT PRIME

169+1=170 NOT PRIME

169+2=171 PRIME

196+1=197 PRIME

196+2=198 NOT PRIME

171+197=368

Find the hypotenuse (which is the side length of the square) via the pythagorean theorem

a²+ b²= c²

^{5^2 +8^2 = c^2 c = sqrt (89)}

Area of square = side^2 sqrt(89)² = 89 units ²

Here is a hint :)

Notice that the triangle is equilateral, and the height of every trapezoid or triangle is the same.

We also know that triangles can be fit together to form trapezoids.

Ty EP :)

I think the question means "write 316 AS square roots" which would get you my answer... I'm not sure though.

Anyone willing to confirm?

Agree with CTG .... strong work !

or did you mean 316 = sqrt(99856) ?

For future uses, the quadratic formula is:

$\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

.

For one solution thie discriminant of the quadratic = 0 b^2 - 4ac = 0

64 - 4 ac = 0

so another equation relating a and c 64 - 4 ac = ac = 16 and given c = 12-a

a (12-a) = 16

-a^2 + 12a - 16 = 0 quadratic formula shows a = 6 - 2sqrt 5

and c = 6 + 2 sqrt 5

The first step to solving it:

$a^2+b^2=1936$

So we get:

$a^2-b^2=704$

$a^2+b^2=1936$

Now we can eliminate a or b :)

Hint: Here are the possible values of a and c. Try plugging them in and solving it.

a=5, c=7

a=4, c=8

a=3, c=9

a=2, c=10

a=1, c=11

Tell me if you need more help :)

Between 10,000 and 99,999, there are 90,000 five-digit integers. Out of that 90,000 there are exactly 24,000 integers that are NOT divisible by any number in the set of {1, 2, 3, 4, 5}, with the exception, of course, of being divisible by 1.

Therefore, the probability is: 24,000 / 90,000 = 4 / 15
